They will flower when they are exposed to a short period of darkness and a long period of light. Long day plants flower in summer and short day plants flower in spring. Examples of short day plants are Glycine max (soyabean), rice, Nicotiana tabacum (tobacco). Examples of long day plants are Brassica campestris (mustard), Raphanus sativus (raddish), Papaver somniferum (opium), Solanum tuberosum (potato).Thus, the correct answer is option C.
